Typical piriformis syndrome symptoms may include:
With prompt diagnosis and treatment, the prognosis is quite good. However, the condition may become chronic; a poor outcome may be more likely if the diagnosis and treatment are delayed. Piriformis syndrome may be the most common cause of sciatic-type back pain you've never heard of; or it may be rare, no one is really sure.
Injuries that can cause the syndrome include:
The correct code for this condition, as answered in AHA's Coding Clinic, is 355.0.
The piriformis muscle connects the lowermost vertebrae with the upper part of the leg after traveling the "sciatic notch," the opening in the pelvic bone that allows the sciatic nerve to travel into the leg. Here, the muscle and nerve are adjacent and this proximity is why trouble can develop.
If you have ever experienced pain, tingling, and/or numbness along your sciatic nerve, you have likely heard the terms piriformis syndrome and sciatica. While these two terms are sometimes used interchangeably, piriformis syndrome and sciatica are not the same and differ in terms of causes, symptoms, and treatments.
Piriformis syndrome is a condition in which the piriformis muscle, located in the buttock region, spasms and causes buttock pain. The piriformis muscle also can irritate the nearby sciatic nerve and cause pain, numbness and tingling along the back of the leg and into the foot (similar to sciatic pain).
Description. Piriformis is a flat muscle and the most superficial muscle of the deep gluteal muscles. It is part of the lateral rotators of the hip (obturator internus, superior and inferior gemelli, quadratus femoris, obturator externus, and gluteus maximus).
The piriformis muscle is a flat, band-like muscle located in the buttocks near the top of the hip joint. This muscle is important in lower body movement because it stabilizes the hip joint and lifts and rotates the thigh away from the body.
Piriformis syndrome is caused by compression of the sciatic nerve as it passes through the buttock. Typically, this occurs from spasm or contracture of the piriformis muscle. When the sciatic nerve is constricted and irritated, the individual will experience the symptoms of piriformis syndrome.
Piriformis syndrome causes pain in the buttocks and hip. It occurs when the piriformis muscle irritates the sciatic nerve. This irritation can cause pain, numbness, tingling, and shooting sensations in the buttocks and hip, and sometimes in the thighs and legs.
While both conditions interfere with sciatic nerve function, sciatica results from spinal dysfunction such as a herniated disc or spinal stenosis. Piriformis syndrome, on the other hand, occurs when the piriformis muscle, located deep in the buttock, compresses the sciatic nerve.
The most important treatment for piriformis syndrome is progressive stretching of the muscle. Your doctor may show you some basic stretching exercises that relax the piriformis, hamstring and hip muscles, increases flexibility, restores range of motion, and allows the muscles to heal.
The primary diagnostic method is having the patient move the hips and legs to identify where the pain occurs. If it is in the lower back and buttocks only, it may be piriformis syndrome. If the pain is in the lower extremity, it is likely sciatica.
Piriformis syndrome is a common cause of low back pain. It is often not included in the differential diagnosis of back, buttock, and leg pain.
